Patented May 3, 1938 UNITED STATES PATENT OFFICE 2 Claims.

This invention. relates to door stops and more particularly to a door stop constructed to constitute a conduit through which electric wires, pipes, cables and the like may be carried for the purpose of performing various operations in a door without interfering with the opening and closing thereof.

In Patent 2,082,449 of June 1, 1937, I have disclosed door stops through which electric wires are extended for the purpose of operating the locks of three of the doors of an automobile from a switch associated with the fourth or master door.

While the door stop of the present invention is primarily intended for use in multiple lock sets, it is none the less true that it is capable of use in many other relations and, in fact, in any relation wherein it is desired to carry power wires, pipes, or cables between two hingedly connected elements.

In the accompanying drawing:

Fig. 1 is a perspective view of a door stop constructed in accordance with the invention;

Fig. 2 is a horizontal sectional view of the same,

, and

Fig. 3 is a vertical sectional view showing the device applied to the door and body of an automobile.

Like numerals designate corresponding parts in all of the figures of the drawing.

Referring to the drawing, 5 designates a curved, tubular member, extended at one end to form the vertical, tubular, 'T-head extension 6. The outer end of the member 5 is preferably threaded for reception of a nut I, and a rubber, fibre or other cushioning washer 8 lies inwardly of the nut l. The vertical extensions of the T, the shank of which is represented by the curved tube 5, is journaled, i. e., pivotally mounted in the horizontal ears 9 and Ill of a supporting plate H.

The plate H is secured by bolts 12 or like fastening devices to the inner side frame member of the car body 13, and said plate has a -'slot I4 to permit lateral swinging movement of the tube 5. It is not essential that a wooden frame member be employed in the car body, but the plate H may be secured to the shell of an all-steel body and the ears 9 and Ii] merely project inwardly of said body.

A fibre or rubber cushioning disk or bushing I5 is preferably secured to the inner side of the side frame member of the door to constitute an abutment for the washer 8, in the cushioning of the opening movement of the door and a guide 5 for tube or shank 5.

As previously stated, this door stop is of general application. It is not even restricted to the passage of electric wires ther-ethrough, but upon the contrary might accommodate a flexio ble tube, such as a rubber hose, through which a pressure fluid could be carried for the purpose of operating the locks or performing other functions by hydraulic power. The same is true with respect topipes for conducting compressed air.

Therefore, it is to be understood that the invention is not limited to the precise construction set forth, but that it includes within its purview whatever changes fairly come within either the terms or the spirit of the appended claims.

Having described my invention, what I claim 1. A door stopcomprising a T-shaped, tubular member, a stop element upon the shank of the T-shaped member, a supporting element comprising a vertical securing plate and horizontally disposed spaced ears integral with said plate and within which ears the head of the T-shaped tubular member is journalecl toturn, said plate being laterally slotted and the said shank passing through the slot of said plate, whereby an electrical conductor may pass through the shank and through the tubular head, as and for the purposes set forth. e

2 A door stop comprising a T-shaped, tubular-member, the bore of which is continuous from the outer end of the shank of said member to and through the head of said T-shaped member, a .stop element upon the shank of the T-shaped member, and a supporting element comprising a pair of spaced plates within which the head of the T-shaped member is journaled to turn about an axis concentric with the bore of said tubular head, whereby an electrical conductor may pass longitudinally through the shank and axially out through the bore of the tubular head, as and for the purposes set forth.
